It's not, i've played this with blanman plenty of times. It's actually hard on both sides becuase it doesn't take long to kill the boss, and it's annoying having to continualy miss with the spartan as the boss. It's super fun to play on and takes a while to get bored of it. Also, the map works with any number of people. You should try it.
Map: The map looks beautifully done, and the aesthetics are great. The rounded area is good and it looks like a final level from back in the good old days. Game: The game is well thought out. I would suggest also doing a Juggernaut gametype and seeing how it plays out. It may be good. Not sure. But the gametype seems fun and well planned. Improvements: (there are definitely improvements, but none of which are immediately obvious. Make a v2 with new ideas) Final Comments and Rating: This map is great and original and fun! 10/10
